To all whom it may concern: f I

Be it known that I, JORGE GrunnRnRo, a citizen of theRepublic of Argentina, residing at 7 Rue Georges-Ville, Paris, France, have invented certain new and useful Improvements in Vehicle-Wheels; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in theart to which it appertains to make and use the same. The present invention has reference to vehicle wheels, and" it -comprehends, briefly, certain improvements, hereinafter specified at length, in or relating to the construction of the rim of the wheel and the devices employed for supporting the tire in place therein, to increase the resiliency of the wheel.

An embodiment ofthe'invention is illustrated in the whereof:

Figure l is a transverse section taken I through the rim of the improved wheel;

Fig. 2 is a similar view of a modification; and Fig. 3 is a section on the line 33 of Fig. 2.

Referring to said drawing, a indicates, generally, the solid tire of the wheel, and b the hollow or trough-shaped rim. The side walls or cheek-pieces b of the latter element are connected by transverse bolts 5 that serve to fasten together the two sections, parts or members of which the rim is preferably composed.

To increase the resiliency of the wheel,

the tire a is so mounted between the aforesaid cheek-pieces b as to be capable of movement in a vertical plane, being carried for this purpose by suitable supporting devices 0 that are disposed transversely of the rim, are structurally separate of one another and are themselves connected to the cheek-pieces. These supporting devices may be made of any desired material, as, for example, rubber or other elastic substance, or steel, and they may be in the form of endless loops, as shown in Fig. 1, or of single bands, strips, or strands, as shown in Fig. 2, as many of the devices being used as may be requ1red. They are engaged at opposite ends with supporting pins cl, or the like,which are mounted on outwardly extending projections with which the cheek-pieces are provided.

In the loop construction represented in Fig. 1, the supporting pins (Z are fastened to Small hollow bosses 03 which fit in openings accompanying drawings,

in the cheek-pieces and are held in place by the tension of the loops, the latter being somewhatstretched consequent upon their application to the rim. WVhere these loops are employed, the tire a is preferably mounted directly upon a supplemental rim o which is of continuous and annular formand is disposed between'the cheek-pieces but is free of positiveconnection therewith, said rim resting directly'iipon the loops. With this form, it is'also preferable to provide means for excluding dirt and other foreign matter from the interior of the main rim I); such means consisting of suitable guards c that bridge the spaces between the adjacent edges of the two rims b and (4 as shown in the edges of the latter rim.

When single bands are used, they are passed throughtransverse openings formed in the tire and are provided at their ends just the tension of the bands, one of the pins may be threaded and passed through a threaded perforation in the adjacent cheele piece, to permit its manipulation.

While the construction just described is satisfactory for general purposes, it is advisable, where the wheel is apt to be subjected to very severe stresses or strains, to provide a supplemental elastic cushion a", so constructed and arranged as to assist the main cushioning devices 0. In the first form of the invention, the cushion of is constituted by a relatively thick annular band or ring of rubber, which encircles and directly engages the bottom wall of the main rim Z2 and is connected with the supplemental rim a by a series of feet or plates a said feet resting upon the said ring, as shown in Fig. 1. Where the modified or second construction is followed, the cushion is constituted by inwardly extending projections formed upon the tire, the bottoms of these projections being normally out of contact with the bottom of the main rim, and in this form, the connecting bolts Z1 pass through the spaces between adjacent projections and do not contact with the faces of said projections or with the bottom face of the tire.

Having fully described my invention, I claim:

1. In a vehicle wheel, the combination, with a trough-shaped rim, and a tire disposed between the cheelopieces thereof; of a supplemental rim wherein said tire Fig. 1, and extend inwardly overand around 1 with yokes that straddle the pin cl. To ad- 7 is directly fitted disposed between said cheek-pieces; a series of transversely 1 arranged yielding devices connected at opposite ends to said cheek-pieces; said supplemental rim resting directly upon said devices; a supplemental cushion encircling-the bottom wall of the first-named "rim; and a;

L series of members connected to said supplemental run and rest ng uponisa idcusln on.

2. In a vehicle wheel, the comb nat on, of

a trough-shaped rim, and a tire disposed between the cheek-pieces thereof; ofa supplemental rim wherein said tire is directly fitted disposed betweensaid cheek pieces; and ser es of transversely arranged elastic loops connected at opposite. ends to sald cheek-pieces; said supplemental rim resting directly upon said loops. 351:1 a vehicle wheel, the combination; with a trough-shapedrim having its cheekpieces provided with removable bosses, said bosses having pins mounted therein of 'a series of transversely arranged elastlc'loops having; their opposite ends engaged V with said plns for dra wing said bosses toward I each other and holding them in place; a supplemental rim disposed between saidcheek-pieces and resting directly upon said loops; and a tire fitted in the supplemental V1668; a. ti fitt d h Supple nta i Y.

an annular cushion encircling the bottom .of the first-named rim; and a series of feet connected to said supplemental rim and resting upon said cushion. i In testimony whereof, I affix my signature, in presence of; twowitnesses.
